Title: Reproducing device for information recording disk
Inventor: YUSA YASUHIRO
IPC: G11B21/21
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a reproduced FM signal having a sufficient level without being influenced by a change in the lapse of time, an adjustment variance, the warp of a disk or the like by making a relative distance between a signal sensor electrode and a disk signal surface variable according to the reproduced FM signal level. CONSTITUTION:When a voltage (a) that the reproduced FM signal, obtained from the disk 19 is converted into a DC level, is lower than a reference voltage (higher than a reference voltage), previously set in a window comparator amplifier 9, the output of a positive polarity (negative polarity) is fetched from the window comparator amplifier 9, and a carrier is raised (lowered) by a carrier height shifting motor 12, and the sensor electrode 2 of a sensor 20 is brought close to (away from) the disk signal surface 4. Thus, even if the sensor electrode 2 is worn by the time aging or the like, the reproduced FM signal with the sufficient level can be obtained, and further, even if the warp or the like exists at the disk 19, the reproduced FM signal with the adequate level can be obtained, and therefore, a turn table 18 can be miniaturized.

Abstract: PURPOSE:To elongate the life of an electrochromic display (ECD) device by adding S<2-> ion to an electrolytic soln. contained in the device to convert metallic ions produced by the electrochemical corrosion of the opposite electrode into insoluble harmless sulfide. CONSTITUTION:A compound having S<2-> ion 10 such as (NH4)2S or H2S as well as an electrolyte such as LiClO4 is added to an electrolytic soln. 8 contained in an ECD device having an opposite electrode 6 formed by pressing electrically conductive particles on a metallic current collector as a core. S<2-> ion converts into insoluble salt by reaction with Pb<2+>, Fe<2+>, Ni<2+> or other ions produced by the electrochemical corrosion of the electrode 6, and it prevents said divalent metallic ion from depositing on the display electrode 1, hindering the adsorption and desorption of Li<+>, reducing the responding speed, and finally making erasion impossible. Thus, an ECD device having a long life is obtd.

Filed: 1983-03-16
Abstract: PURPOSE:To obtain a sputtering target structure facilitating the cooling and exchange of the target without leaking cooling water by fastening a target on a water cooling backing plate with a heat transferring soft metallic medium in- between. CONSTITUTION:A backing plate 16 is screwed on a cathode 14 having built-in magnets 9 and contg. cooling water 17.

Title: Glowing method of flux-inert gas mixture
Inventor: OOSUMI KENJI
IPC: C22B9/10
Filed: 1982-03-17
Abstract: PURPOSE:To prevent the decrease of the blowing efficiency and refining yield due to the clogging of a lance by heating a mixture of a refining flux-inert gas to a temperature higher than the vaporization temp. of the flux at the blowing of said mixture. CONSTITUTION:In refining the molten metal of nonferrous metal and its alloy, the mixture of the flux-inert gas is transferred through a rubber hose 3 to the lance 1 connected by a joint 4. The mixture passes through a heater 2 composed of refractories etc. having kanthal wire therein and is blown into the molten metal M from the tip of the lance 1 after the vaporization of the one part or whole of the flux. Since the temp. in the lance 1 is high, the mixture is blown in without the precipitation of the vaporized flux. Thereby, since the melting of the flux in the lance 1 doesn't occur, the blowing in operation is stabilized and the yield of the flux is increased.

Title: Microcomputer
Inventor: KAWADA KAZUHIDE
IPC: G06F11/22
Filed: 1985-03-04
Abstract: PURPOSE:To test the function of an instruction sequence in a ROM by a customer's program by providing a means for ignoring a branch instruction, a skip instruction, and a data setting instruction to a memory which are read out of the ROM. CONSTITUTION:The customer's program stored in the ROM 1 is sent out to an instruction decoder 5 successively from the address '0' and a microcomputer operates. In this case, when the branch instruction is sent out of the ROM 1 to the decoder 5, a branch instruction inhibiting signal S5 is outputted and this instruction is ignored by an AND gate 9. Further, when the skip instruction is sent from the ROM 1 to the decoder 5, a skip instruction inhibiting signal S7 is outputted and a judging signal S3 is ignored. Therefore, even when the customer's program has a loop, the loop is ignored and instructions of the program stored in the ROM 1 are executed from the address '0' to the final address.

Title: Temperature control device
Inventor: KOJIMA SUZUO
IPC: H05B3/00
Filed: 1978-04-10
Abstract: PURPOSE:To trigger a triode AC switch in zero phase of a power supply voltage using a follow-up trigger system for triggering in next positive half-cycle when a triode AC switch triggers in negative half-cycle by setting a heat sensitive thyristor at the same potential as one terminal of an AC power supply. CONSTITUTION:When the temperature of an article to be heated is lower than predetermined temperature, first capacitor 41 is charged at the polarity shown during the positive half-cycle of an AC power supply 1. When the power supply phase tends to invert, the leading current of the capacitor 41 is flown through the gate of an auxiliary thyristor 6 since a heat sensitive thyristor 4 is OFF to thereby trigger it in zero phase of the power supply. A gate current will flow through a triode AC switch 3 in a loop of  the power supply 1 - heater 2 - the terminal T1 of the triode AC switch 3 - gate - auxiliary thyristor 6 - power supply 1 to cause the triode AC switch 3 to become ON. Thus, a half-wave current will flow through the heater 2.

Abstract: PURPOSE:To obtain an electronic apparatus which can be operated easily, by constituting it so that a contrast adjusting means and an inclination angle adjusting means can be interlocked. CONSTITUTION:A shaft 12 is used for varying a resistance value of a rotary volume 11 and directly coupled with a supporting shaft 4 of a display device by a joint 14.

The resistance value of the volume 11 is changed so that an optimum contrast is obtained at the time of a rotational angle thetaalpha of the display device 2, at which the most easily visible visual angle of field alpha is obtained. A relation of the optimum angle of field alpha and a turning angle of the shaft 12 for obtaining the optimum contrast is set by an initial adjustment of the joint 14. According to this constitution, an operator can allow the liquid crystal plate 5 to hold the optimum contrast by only adjusting the volume to match his own angle of field alpha, and only raising up the display device to the angle alpha at the time of use.
